Rockola Legend stuck on S-1

[shaundburch]

Hi Folks.  First time poster.  A buddy of mine recommended asking my question here.

Looking for some advice with an issue I'm having. It's a Rockola Legend 6000X CD. It will power up and cycle thru the codes, ending on S-1. From what I understand, that means it's ready for normal operation.



I pulled the main board and found the battery had corroded and bled out. I removed the battery, cleaned up the board, and check all the traces for damage. Everything looks good. I wired up a rechargeable battery pack and mounted it external to the board.



Fired up the juke again, same problem. Looking over the manual, at this point you are supposed to slide the scan switch to the "OPER" position and move switch 10 on the main board to the "on" position to get it to read the discs (assuming the programming was gone). No luck there.



In addition, I can't interact with the control board via the buttons and the page buttons won't turn the pages.



I followed connections to the mech control PCB, and neither of the LEDs are lit. The +5 looks good at the test point on that board, but voltages seem low around other components.
  Checking the 26V test point gives me about 1.8 volts.  Is it safe to assume both LEDs should be lit up?


So that's where I'm at.  I need to figure out where the power is coming in, and verify that's good before I worry about replacing the board.


If anyone has any input, let me know. Very much appreciated!

Shaun,
Did you wash the board that the battery bled on, with hot, soapy water-- and/or rubbing alcohol ?  That "stuff" tends to get under "chips" and short out traces--Be 200 % sure it is dry prior to power up---
Just GUESSING-- I would assume LED's should light to indicate that power is there--but I would NOT assume, that a lit LED indicated that the CORRECT power was there-- if possible, start un-plugging "down-line" items, to see if/where, the LED's light-- Ron Rich

Hi Rich,

Thanks for the response!

Yes, I cleaned up the board really well. I'm used to seeing this kind of thing in pinball games and old arcade machines, so it's the only thing that was familiar for me :-)

I agree, since the LEDs are not lit on the pcb...it's either an issue with the power being fed to the pcb or an issue with components on the board itself. I just need to figure out which.

Thanks again,
